Fractional integration with singularity on Light-cone,I: natural setting
Zipeng Wang
In this first part of our project, we prove a classical Hardy-Littlewood-Sobolev result for a new family of fractional integral operators whose kernel has singularity appeared on t…
Fractional integration with singularity on Light-cone, II
Zipeng Wang
In this paper, we study a family of fractional integral operators whose kernel carrying a critical index has singularity on the light-cone in R^n+1.
The theta bump condition for product fractional integrals
Eric T. Sawyer, Zipeng Wang
We extend some one parameter theorems on fractional integrals due to Sawyer and Wheeden to the two parameter setting using a recent iteration method of Tanaka and Yabuta.
On the Controllability of Lagrangian Systems by Active Constraints
Alberto Bressan, Zipeng Wang
We consider a mechanical system which is controlled by means of moving constraints. Namely, we assume that some of the coordinates can be directly assigned as functions of time by…
